SPRAYING DEVICE.

Application filed November 21, 1910. Serial No. 593,325.

To all whom it may concern:

Be it known that I, HENRY E. BRANDT, a

citizen of the United States, residing at Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in Spraying Devices; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

My invention has for its object to provide an extremely simple andhighly eflicient s ora in device adated to be carried in one ;1 s P handand operated by the other and, to such ends, the invention consists ofthe novel devices, construction and arrangement of parts hereinafterdescribed and defined in the claims.

Particularly, this invention relates to small spraying devices employinga cylinder and piston pump and with a liquid contain-- ing tank attacheddirectly to the pump cylinder. In devices of this kind, as hithertoconstructed, it has been customary to provide the liquid tank with asmall diametrically extended discharge tube, the upper end of whichterminates close to a small air discharge passage in the delivery end ofthe pump cylinder. This small liquid delivery 5 tube must be accuratelyset in the tank with its end projecting just at the right place in ffront of the air passage, so that the proper setting of the tube hasrequired considerable time and care, in spite of which frequently,because of inaccuracy, devices thus constructed do not operate properly.My invention provides a much cheaper and much better arrangement as asubstitute for the tube and which may be'properly and accuratelyadjusted with but very little care.

In the accompanying drawings which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view partly in side elevationand partly in vertical section, showing the improved sprayer; Fig. 2 isa fragmentary vertical section taken on the same line as the section ofFig. 1, but showing the parts on a larger scale; Fig. 3 is a horizontalsection taken on the line 00 w of Fig. 2, some parts. being broken away;Fig. 4 is a view corresponding to Fig. 2, but illustrating a slightlymodified construction; and Fig. 5 is a horizontal section taken on theline 10 x of Fig. 4, some parts being broken away.

The numeral 1 indicates the pump cylin- -der provided in the head at itsdelivery end, near the bottom thereof, with a small air dis- ;chargepassage 2. In the other end of the fcylinder 1 is a guide plug 3 ofsuitable con-' lstruction. Working within the cylinder is a piston 4:,preferably provided with the fiusual self-seating flexible packing 5,and ihaving a stem 6 that works through the guide plug 3 and is providedwith the cusgtomary hand piece 7.

The tank 8, which will contain the liquid @130 be sprayed, is preferablya cylindrical Estructure having its axis parallel to the axis jof thepump cylinder and having its upper iportion soldered or otherwiserigidly secured ito the said pump cylinder with its front end projectingslightly beyond the front end of ithe said cylinder. The rear head ofthe tank f8 is provided with a threaded filling nipple 9 fnormallytightly closed by a screw threaded ,icap 10. The front head 11 of thetank 8 is provided with a cylindrical flange 12 that is telescoped overthe end of the cylindrical tank and, at its extreme edge, is securedthereto with a water tight joint, preferably iby solder.

The description so far given applies to both forms of the deviceillustrated.

In the construction illustrated in Figs. 31, 2 and 3, the cylindricalbody of the tank .8, in that portion which is surrounded by the flange12, is formed with an annular inwardly pressed bead affording a waterdelivery channel 13 which extends from top to bottom of the tank, or, infact, completely around the tank and is in communication with the bottomof the tank through one or more perforations 14 formed in the saidinwardly pressed bead or channel 13. The flange 12, at a pointimmediately in front of the air discharge passage 3 of the pumpcylinder, is bulged slightly outward and upward and provided with aliquid discharge passage 15, which latter is 10- cated in line with andjust in front of the said air passage 2, so that the-air discharged fromthe pump will be blown immediately across the top of the said liquiddelivery passage 15 and thereby draw liquid from the tank and deliverthe same in the form of a spray. The best results are produced by theuse of the continuous or endless liq- Patented Jan. 30, 1912. i

uid delivery channel 13, because, with this arrangement, the water willbe drawn upward from the tank in opposite directions invention toprovide the tank with this liquid delivery channel only at one side, or,in other words, to extend the said channel throughout only approximately180- The construction illustrated in Figs. 4 and 5 is like that abovedescribed, except that the endless channel for the delivery of theliquid is formed by pressing a bead 13 outward in the flange 12 of thehead 11 and in providing the said bead 13 at a point just in front ofthe air delivery passage 2 with the water discharge passage 15*. As

be formed by coincident beads formed both in the tank and in thesurrounding flange of the tank head.

In practice, I have found that this improved spraying device will workmuch more satisfactorily than a similar spraying device having the usualdiametrically extended liquid discharge tube at its lower end, spacedapart from the bottom of the tank. It has been found possible todischarge all, or substantially all of the contents of the tank with theapparatus directed upward, if in the operation it be occasionallyinverted to charge the channel 13. In explanation of this operation, it

liquid when turned downward, and this liquid will be discharged when thedelivery 'end of the device is turned upward and the pump applied.

A spraying device of the kind described will be found useful forspraying various liquids, but is'especially adapted for use for sprayinggermicide or fungus destroy- 7, ing liquids on plants and the like.

The manner of applying the crease or head to formthe liquid conveyingchannel in the tank materially reduces the cost of the spraying deviceand, as already indicated, at the same time, gives greatly improvedresults.

What I claim is:

1. In a spraying device, a liquid containing tank provided-with aflanged head secured thereto and having a circumferentially extendedliquid discharge channel formed between thebody of said tank and thesurrounding flange of said head, and the said channel havingcommunication with the interior of the tank at one point and having adischarge passage located at a distant point.

2. In aspraying device, the combination with a cylinder and piston pump,of a tank secured to the pump cylinder with one end projecting beyondthe delivery end of the latter, av head having a flange telescoped withthe projecting end of said tank, a liquid delivery channel being formedbe- ,tween the projecting end of said tank and the flange of said head,the said channel havingv communication with the interior of the saidtank and having a discharge passage at its upper portion and thedelivery end of said cylinder having an air discharge passage located inthe Vicinity of the discharge passage of said liquid delivery .channel.is obvious, the water delivery channel might 3. In a spraying device,the combination with a cylinder and piston pump, of an approximatelycylindrical tank secured to the pump cylinder with one end projectingbeyond the delivery end of the latter, and a :head having a flangetelescoped over the projecting end of said tank, an endless liquiddelivery channel being formed be- ;jtween the projecting end of saidtank and ithe surrounding flange of said head, the said endless liquiddelivery channel having Ecommunication with the interior of said :tankand provided at its upper portion with ia liquid delivery passage, andthe said lpump cylinder in its delivery end having an iair dischargepassage located in the Vicinity may be stated that the channel 13 fillswith of the discharge passage of said liquid delivery channel.

l. In a spraying device, the combination with a cylinder and pistonpump, of an approximately cylindrical tank secured to the cylinder ofsaid pump, the said pump having in its delivery end an air dischargepassage, andv a flanged head telescoped over the end of said tank, thebody of said tank .being provided with an inwardly pressed endlessgroove having communication with the interior of the tank and affordinga liquid delivery passage, and the flange of said head having a bulgedupper portion with a perforation affording a liquid delivery passagethat is located in the vicinity of the air discharge passage of saidpump cylinder.

In testimony whereof I aflix my signature in presence of two witnesses.
